# Circuit Trace Hero

> A hero section that is a printed circuit board. Your copy sits in a silkscreen keep-out zone while, beside it, copper traces route themselves from a main chip with your name etched on it to smaller chips, vias and off the board's edge, then light pulses run along the buses in bursts and a status LED blinks. A small router built into the page lays clean 45-degree paths that never cross. Your agent sets the mask, copper, silkscreen and pulse colors, fonts, logo, chip label and board text, checks contrast at four widths and records a seamless 1080p loop.

- Output: Web, Animated hero section · page + embed + 1080p video
- Price: $6.90 one-time, or included in Pro
- Page: https://lookbk.dev/skills/circuit-trace-hero

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge, for the checks and the recording (the scripts find it; set `CHROME_PATH` if they don't).
- ffmpeg, for the video (`brew install ffmpeg`, `winget install ffmpeg`, `apt install ffmpeg`; or set `FFMPEG_PATH`).
- At runtime, nothing but a 2D canvas: the drawing code is inlined in the page. Fonts load from jsDelivr (the pinned list) or Google Fonts; without the network the page uses system fonts.

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add circuit-trace-hero
```

The first run prints a sign-in link; open it, approve, and run the command again. Pro skills install for accounts that bought them or have Pro.

Where it installs:

- Run by Claude Code: `~/.claude/skills/circuit-trace-hero` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/circuit-trace-hero`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/circuit-trace-hero` when `~/.claude` exists.

Add `--claude` or `--shared` to write only one of those folders, or `--project` to install into the current folder instead. Start a new agent session afterwards so it picks up the skill.
